The specimens of this in the Leiden Herbarium, on which Ondemanns founded this
species, are very fragmentary indeed. It is represented in M. De Caudolle's herbarium
b y a few fruits, and is (1887) quite unrepresented at Kew and the British Museum.
I n Perak the tree appears to be tolerably common; and the Perak specimens differ in
no respect from the Javanese, escept in having the glans quite glabrous when ripe.

Young branches minutely pTiberulous. Leaves coriaceous, elliptic-oblong, shortly and
rather abruptly acuminate, entire; the base acute; when young both surfaces minutely
pubemlouB-lepidote; when adult almost glabrous; the upper surface dull; the lower pale
and slightly shining; midrib and about 9 pairs of nerves bold and faintly coloured on
the lowei' surface; length of blade 6 to 8 in., breadth 2-25 in. to 3 in., petiole '6 in. to

pedicel, campanulate-hemispheric, embracing more than half the glans, with 5 to 7

According to the technical characters founded on the cupulo this is a Cyclohalamm
but its real affinities are with Q. Amherstiana, Falconeri and scijphigera, which are Pasanias.
The late Dr, Scheffer, the author of this species, explains (I.e. iii. 9-1) that when he first
described it he associated with its leaves the flower and fruit of a different species which
had by mistake been fastened on to the same sheet. On the subsequent receipt of
specimens bearing leaves and fruit he re-described the species. The specimens from which
I have written the foregoing description bear the number 11443 of the Herb. Ilort. Bot
Bogor. According to Dr. SchefFer, the ripe fruit often measures I'O in. in diameter, but
I have seen none measuring more than 1 in.

Young parts minutely lepidote-canescent. Leaves coriaceous, oblong-lanceolate, bluntly
acuminate, entire; the base acuminate; upper surface glabrous shining, the nerves
obscure, the midi-ib distinct; under sm-face paler, dull, minutely canescent, the midrib
thick and prominent; main nerves 7 to 10 pairs, sub-glabrous, and dark-coloui-ed, as are
the secondary and minor nerves; length of biade 3-5 in. to 5 in., breadth 1-4 in. to 1-8

pubescent; the flowers interruptedly glomerulate. Female spikes longer than the leaves,
terminal or axillary. Cupules minutely sericeous, solitary, on long stout peduncles; when
young sub-globular, enveloping the whole of the young glans except its apex; when
adult shallow, campanulate (or even saucer-shaped when very old), narrowing at the
base into the thick annulated peduncle; lamellas about 7, the lowest the broadest; their

Of this species there are very few examples in collections. The leaves of Korthals'
and Miquel's specimens in the collections at Leiden and Utrecht have from 10 to 12
pairs of nerves, while Teysmann's Bornean specimens have only 7 to 8 pairs. Moreover,
the secondary nerves of the Sumatra specimens are nearly as large and distinct as the
primary nerves ; and the reticulations are also prominent, which is not the case in the
Bomean plants. Nevertheless, I think the two sets are referable to one species. Korthals'
specimens have no ripe fruit, and the fruit of Teysmann's appears to be scai-cely ripe.
But, as far as the materials go, the two sets agree in fruit.
